Harbaugh on Alex Smith’s sprained finger: “It’s very much a concern.”

SANTA CLARA – Jim Harbaugh spoke for 20 minutes in the defensive meeting room Monday afternoon. Instead of posting the entire transcript in one blog, I’m breaking it up by theme to focus the discussion.

Here’s what Harbaugh said about the sprained middle finger on Alex Smith’s throwing hand. Smith sprained it in the fourth quarter on his final pass attempt of the 49ers 45-3 victory over the Buffalo Bills.

HARBAUGH: It’s very much a concern. We’ll see how it is. It’s well documented how tough he is. He talks about it not being a big deal, so we’ll see.
